[求助] 翻譯幾句英文，我不能理解，可否解釋一下。陶瓷，氧化鋁，粉末微注射法相關(guān)

In the case of ceramic powder where finer particle
size is more easily available, there is a need to develop feedstocks
from powder of submicron or nano-particle size in order
to exploit the full potential of micro PIM. Processing such fine
particle size, especially nano-particles, poses problems because
of its large specific surface area and the associated tendency to
agglomerate. With the use of finer particle size more binder is
required to coat the surfaces of the particles and this can increase
the final shrinkage after sintering. In a survey of available powders,
only some powders are available in submicron particle size
and some examples are copper, iron, tungsten, cobalt, zirconia,
alumina and tungsten carbide. The general rule is that the minimum
feature that can be produced is ten times the particle size.
Thus, to produce smaller features or structural details, finer particle
size is required.
重點(diǎn)是最后兩句，不理解什么意思

一般規(guī)律就是，可制備的最小外形尺寸是粒子尺寸的10倍。因此，為了制備更小的外形或結(jié)構(gòu)型材料，需要更好（�。┑牧Ｗ映叽�
